Short answer: the W-King X10, though neither ranks well in its class. It ranks #77 of 89 boombox speakers by sound quality, rated 2.3/5, at $80; the Zealot S78 ranks #88, rated 2.0/5, and costs $159.68, so there is not much of a tradeoff to weigh. Both are rated below 3.0/5 among the 89 boombox speakers, and the Tribit Stormbox Blast, ranked #2 at $179.99, is a better place to start if sound quality matters.
The case for the W-King X10: 70W RMS output with 120W peak power, exceptional 42-hour battery life, power bank function, IPX6 waterproof, 106dB max volume, EQ with indoor/outdoor modes, dual woofers with tweeters and passive radiators, Bluetooth 5.0 with 100ft range, MicroSD and USB playback, AUX input, TWS stereo pairing. The tradeoff: Heavily rolled off treble, less bass than the top ranked.
Why pick the Zealot S78: A robust 4.4kg party speaker with claimed 120W RMS output, IP67 protection, USB-C charging, a power-bank function, aux, USB and microSD playback, TWS pairing and multiple EQ modes. The tradeoff: At high volume, reviews report distortion and fluctuating level, so its headline power is more useful below its maximum setting.
Buy the W-King X10. It is rated higher for sound quality than the Zealot S78 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Zealot S78: $159.68 Amazon AliExpress eBay
Pros: A robust 4.4kg party speaker with claimed 120W RMS output, IP67 protection, USB-C charging, a power-bank function, aux, USB and microSD playback, TWS pairing and multiple EQ modes. Reviews find it very loud with useful bass and long claimed battery life, making it a credible choice for outdoor gatherings.
Cons: At high volume, reviews report distortion and fluctuating level, so its headline power is more useful below its maximum setting. It has no app-based EQ, and the bass and midrange refinement do not match better-established boombox speakers; assess its sound in person if tonal accuracy matters.
